JOHN E. TOOHEY, F GRAND RAPIDS, MICHIGAN.

ERAMING-MACHIN E.

Be it known that I, JOHN EfToorInY, a citizen of the United States of America,'residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Fraining-hlachines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a framing machine of especial value and utility in framing timbers such as are used in building trestle work and the like for railroad bridges. It is the object and purpose of my invention to provide a device of this character which will consist of an attachment that may be readily secured to or removed from the ordinary hand car which section gangs on railroads use, and the device may be operated by a gasolene engine which furnishes the motive power for the hand car. A further object of the. invention consists in the provision of an attachment of this kind which may be very cheaply and easily manufactured consisting of few parts but of durable natureso as to withstand themore or less rough usage to which it may be subjected. To these ends I have constructed a device. the structure and operation of which is illustrated in the accompanying drawings. in which:

Figure 1 is an elevation showing my attachment applied to a hand car and the method of its use.

Fig. 2 is a sectional view taken on the line 22 of Fig. 1 and looking in the direction ind cated by the arrows.

Fig. 3 is a view on a larger scale showing the opposite side of the attachment from that shown in Fig. 1; and

Fig.4 is a plan view of said attachment.

Like reference characters refer to like parts throughout the several views of the d ra wings.

My invention is adapted to he applied'to a hand car, the platform of which is indicated at 1. it being movably supported by the usual wheels 20 so that it may be moved over railroad tracks. An internal combustion engine indicated at 3 is located above the platform and may be of any conventional construction including a shaft 3 on which the fly wheels 4 are mounted. A drive wheel 5 is also secured to the shaft 3 adjacent one of the fly wheels and by means of Specification of Letters Patent.

a belt interposed between this wheel and a shaft on which the wheels 2 are mounted; it

will be evident that the engine may propel the hand car over the suitable tracks. In practice the engine is secured to a base timber 6 which lies lengthwise and centrally of the platform of the car. 1

The attachment which I use in connection with the hand car for framing timbers includes a support 7 made preferably from cast iron, its upper end beingformed with a bearing 8 to receive a pin 9.. A pair of spaced apart bars are used which are pivotally'mounted upon the pin 9, one at either side of the bearing 8, it being evident that these bars may be detached at any time by withdrawing one of thecotter pins 11, so that the pin 9 may be readily removed. Bars 10 extend forwardly a distance beyond the end of the platform 1 and at their outer ends are connected by a block 12 also preferably formed of cast iron though the material used may be varied. Between the ends of the bars 10 another block 13 is secured serving to brace and strengthen the structure as a whole and also serving an additio alfu ction wh ch will later be de cribed.

The block 12 is bored to. form a bearing for the cross shaft 14 one end of which may have attached thereto any suitable rotary cutter such as indicated at 15 while the opposite end carries a small drive pulley 16, an endless belt; 17 passing around the drive wheel 5 and the pulley 16 serving as a means for driving the shaft 14 and the cutter thereon. A guard rod 18 is attached to one of the bars 10 serving to hold the belt in place against any accidental removal from the pulley 16 while the opposite bar has a guard 19 of substantially the formation shown in Fig. 1 against which chips or the like thrown from the cutter 15 strike. stopping them from getti g on to the car platform or the engine. Th s guard is attached to the side 10 by a suitable angle bracket; indicated tit-20.

The block 13 has passing therethrough an uprig t screw threaded shaft 21. the upper end of which carries a hand wheel 22 while its lower end bears upon a metal plate 23 attached to the member 6. Anv suitable interiorlv screw threaded nut is formed in the block 13 for the reception of the screw and it will be evident that by operating handle 22 the cutter 15 may be raised or lowered to any desired position between certain line.-

i its. It will be further evident that the'cutter 15 maybe of any desired'type and asit is removably attached to the shaft l tmay In the use of the mechanism for framing timbers a platform is provided as indicated at 24 on which short lengths of rails 25 are secured for carrying the hand car. A hantile 26 is detachably attached to one of the wheels 2 by means of the hooks 27 engaging with two of the s'pokes of the wheel, these hooks being tightly engaged with the spokes on tightening the nuts 28 on the ends of the screws as'shown in Fig. 2. By loosening the nutsthehandle may be entirely removed from the hand caras when it is to be used to traverse a track. In front of the platform 24 a truck 29 is positioned being mounted on rails 30 so as to move back andforth in front of the platform. A timber 31 is laid on the truck and brought to any desired position for framing. lVith the cutter 15 in motion and driven by the engine it will be evident that as it is moved back and forth across the timber it will cut ma terial therefrom and the depth ofthe cut may be regulatedby' operating the screw and forth in front of'the cutter 15, By

' grasping the handle 26 the car withthe attachment thereon is moved back and forth to carry the cutter across the timber and a straight. out such as indicatedby the dotted outline 32 is made.

With this constructiontirnbers may be very rapidly framed without the use of skilled, labor and the framing will be equal Copies of this patent may be obtained for to or better than i that produced by most I skilled laborers.

The attachment maybe readily removed from the car by merely,

i withdrawing the pin 9 and vremoving the .handle 26 whereupon the car may be used to traverse a track 1n the usual manner and it can be quite as easily added when desired for the purp ose of framing timbers. This attachment is of very simple construction but one of'great utility as has been found in actual practiceovera period of several months. Slight changes in vminor details of construction may be resorted to c without departing from the invention which is defined in the appended claim. Accordingly I do not wish to be'limited' to the exact construction shown but consider myself en-' titled to all modificationsfalling within the car a limited distance in either direction, a

motor on the car, a member mounted on and pro ectmg' n front of the car,ac shaft carried 1n the forward end ofthe member, a

rotary cutter attached to the shaft, means 7 to drive the shaft from themotor whereby said shaft and cutter thereon may operate V simultaneously-with the movement of the car, and a work holding trucklocated in front of said car and mounted to movelin a direction transverse to the movement, of c the car, said cutter lying above the truck, and said truck adaptedto carry the work operated upon by the cutterysustantially"as and for the purpose described." 1

V In testimony whereof I ailix mysig'nature.
